Ranger - "Higher Vampire" [5th Campaign, 5th Mission]

I'm playing as a hero, and I'm currently playing this mission for about 1.5 hours a day. In-game, it's the 2nd month, 3rd or 4th week. I've already captured 2 artifacts from the dwarves, and I took Orange a long time ago; there were no problems capturing it at all. Either Ravenna or Orson attacked me, and they were defeated when I managed to eliminate all the archers, about 1.5k of them :D

And right now, I'm playing and noticed that Nicholas is having a blast with my hero :D. He's running around with the entire army, and it's still Ravenna, while Nicholas is running around with only 2 Cave Lords!!! :DD (I wonder where he got them).
